The description below somehow implies that you can get 2 rares for just 1 instance of logging in 10 days. You get Papel Box, which gets you one random Papel Rare and 30 keys. You get another random Papel Rare again by simply logging in at 10th day. (???) That sounded too good to be true. Please enlighten me whether this description is true or merely

I eventually opened 2 pouches, because the first one yielded a plain Lucky Set #11. Of course I stopped opening the rest of the pouches again, as the 2nd one yielded Ancient Dark Wings (Cecilia) . I already have wings of same effect (Ignition Booster as part of Atomic Set) for her, so it's useless for me. Still, a win is a win... That makes 2/3
